Dual Diagnosis
The simultaneous presence of a substance use disorder and a mental health disorder, requiring integrated treatment approaches.
Full Definition
Dual diagnosis, also known as co-occurring disorders or comorbidity, describes the condition where an individual experiences both a substance use disorder and a mental health disorder simultaneously. These conditions often interact in complex ways, with each potentially triggering or exacerbating the other. Common dual diagnosis combinations include depression with alcohol use disorder, bipolar disorder with cocaine use, or PTSD with opioid use disorder. Treatment requires integrated approaches that address both conditions concurrently rather than treating them as separate issues.
Usage
Usage note: Prefer 'co-occurring disorders' in formal clinical documentation.
